Singer was among the very first to study the cosmic radiation outside of the Earth's atmosphere using rocket-borne instruments. He developed the method used to date the origin of meteorites, and demonstrated how the Moon might have been captured to become a companion of the Earth. He pioneered instrumented satellites before Sputnik and devised instruments for measuring ozone and other atmospheric constituents from space.[1]

In rebuke to the EPA classifying CO2 a health hazard, Singer says “Its science is based primarily on the United Nation’s Intergovernmental Panel on Climate Change, (and) the IPCC conclusion about the human cause of climate change is not supported by any kind of credible evidence. None whatsever,” [2]
